Where there's presentations that will be used multiple times and for difference audiences, there's a need to change the direction of the presentation, or change the order.

Examples:

Start out presentation and based on Q&A feedback, can choose presentation path 1, 2 or 3

Start out presentation and based on Q&A feedback, fast-forward sections automatically to next topic

Start out presentation and based on Q&A feedback or "more info" click option, insert "alternate slides" to jump to to delve into the topic further

I appreciate it requires more design upfront to arrange this but helps with dynamic direction of the meeting based on audience interest (or dis-interest) on the topics
